  • Remote power trouble

    Quote from TheChief

    It freezes in LE and with Android. Without your u-boot.bin everything works as expected (except power on with LE). So i dont think, its the power supply. I would like to debug, but i dont know how. Now i'm back on the original Freaktab firmware. How can i get the log about RAM? Do i need e serial connection? Tutorial somewhere?

    Use uart for logging (see page 7)

    Which DTB file did you use?

    Thank you. Now Power on/off works with LE. Have to check Android on internal again, after some minutes keyboard/RC does not reponse. System seems to be freezed. I used the ChimeyJimmey method.

    Now LE also freezed. How can i debug and help? With ADB? How can i get the bootloader log?

    EDIT:

    Could i have this RAM chip? Found one single chip with D9TXF printed on. Clock rate 933Mzh, Data rate: DDR3-1866

    Check the power supply. So far none of the users complained about it

  • Remote power trouble

    There are two reasons for this. 1. The remote control code does not match the code in the bootloader. 2. Your power supply is poor quality or slightly weak.

    So you can tell if the power supply is not ok.

    - Pull out the HDMI cable on the box.

    - Turn on the box and wait until it has completely booted.

    - Then switch off the box by remote control again.

    - After switching off, try switching the box on by remote control.

    When the box starts up, it's up to the bad power supply.

    Please post your remote.conf file

    Remote power trouble

    Maybe i dont understand it right. I boot with my normal LE sdcard, write zero to /dev/env and /dev/bootloader and than i insert the Emergency System and write the new boot loader?

    Correctly

    Quote

    Did i forget something, because if i power off without a bootloader, the system doesnt boot? Or should it boot from SDCard2? Because in my case, it didnt work and i had to restore via USB Burning tool

    it should boot from the sdcard2. Please note - the bootloader in the installation guide is only suitable for devices with LPDDR3 memory (blue pcb v5 and v6).

    after that i cannot power on with remote

    1. Therefore, you should test the two versions and not search other forums. So it is very difficult to help someone. uboot gt1 does not support * 3g.dtb, the manufacturer did not integrate it for whatever reason

    Code
    Find match dtb: 0

    for * 3g.dtb support there should be a "1" in the place

    2. this uboot does not contain a custom suspend FW and there seems to be a problem with the size calculation. It should only serve for testing to locate the bug.

    The bug is localized, we just have to figure out the most suitable frequency rate. Wait for the update.

    you have strange DDR4, I have the feeling that your DDR4 ≠ is a real DDR4.

    We can try to gradually reduce the Clk rate and hope it works

    Please only test u-boot.bin.sd.bin, it makes no sense at the moment to install u-boot.bin in emmc.

    u-boot@696Mhz

    I will provide it a little later.

    and is there a way to update only the uboot on sdcard, so i must not destroy my internal? iam afraid to do this...

    LibreELEC-S912.arm-8.90.6-h96pp-emergency-sdcard.img.tar seems to be broken... i can't unpack with rar or zip, says after 97% error.. have downloaded it twice...

    gunzip runs 30mins and more an no ending...

    1. u-boot.bin.sd.bin can only be operated if the internal boot medium (emmc / nand) does not contain a bootloader .. is empty

    see Amlogic S912 datasheet

    2. extract this with 7-zip

    Updating u-boot.bin.sd.bin:

    Code
    dd if=/dev/zero of=/dev/sdX bs=1 count=442
dd if=/dev/zero of=/dev/sdX bs=512 skip=1 seek=1 count=2047
dd if=u-boot.bin.sd.bin of=/dev/sdX bs=1 count=442
dd if=u-boot.bin.sd.bin of=/dev/sdX bs=512 skip=1 seek=1
